Heat resistance is an important characteristic of many electromechanical devices. Conductive slip rings, which are widely used in electromechanical equipment, sometimes also need to have certain heat resistance characteristics. For example, conductive slip rings used in construction equipment specifically designed for heavy-duty applications must have heat resistance to meet the demands of operation in the cold regions of Siberia and the hot rainforests of Brazil. As an experienced international slip ring manufacturer, JINPAT has developed a variety of conductive slip rings with high and low temperature resistance.

In addition to extreme high and low ambient temperatures in natural environments, there are also many electromechanical devices that operate in specially designed high-temperature environments, and the conductive slip rings used on this equipment naturally need to be as heat resistant as the equipment itself. To achieve the appropriate level of resistance to high and low temperatures, these conductive slip rings are subject to much more stringent material selection requirements for key components such as housing, bearings and brushes than conventional conductive slip rings. Of course, their mechanism design is also different from conventional slip rings.

Among the high-temperature and low-temperature resistant conductive slip rings developed by JINPAT, there are products that operate in extremely high and low temperature environments for long periods of time. An example is the high-temperature conductive slip ring developed by JINPAT for high-temperature rollers. It operates in an environment with a constant temperature of more than 100℃ for a long time. For the development of this product, JINPAT, in cooperation with a constant temperature box manufacturer, specially developed an ultra-high temperature life test bench and completed its full test after several months. However, the temperature above 100 ℃ does not reach the limit temperature for some electromechanical devices, and some conductive slip rings can be immersed in an environment with temperature above 200 ℃ for operation.

With experience in developing conductive slip rings for constant temperature and high temperature rollers above 100 ℃, JINPAT continues to develop slip rings suitable for use at higher temperatures. A typical example of success is JINPAT’s conductive slip ring, which can operate in ultra-hot silicone oil environment at temperatures above 200℃. Its model is LPT 012-0802-HT, which is produced in a relatively small volume. In order to better monitor the wear of the friction pair with conductive slip ring, this type of product is designed with a hole on the outer shell, which is similar to the ultrafast conductive slip ring developed by JINPAT, but for other purposes. The former can be used for observation, while the latter is used both for observation and for heat dissipation and cold air supply.

In addition to the conductive slip rings used in specific scenarios or equipment, many conductive slip rings also have high impact resistance requirements at high and low temperatures. Many models of conductive slip rings are designed to withstand short-term high and low temperature impacts from -60 ℃ to +120 ℃, while for some products, conductive slip rings must also withstand short-term temperature impacts from -100 ℃ to +180 ℃ under vacuum conditions. With a complete set of high and low temperature testing equipment and an experienced team of engineers and technicians, JINPAT is also able to complete the design and development of this conductive slip ring.
